"Definitely, she heard us," said Linda Saunders-McLean, who believes the hands waving in the window belonged to Hunter.

"You could see that probably really gave her that incentive to keep doing what she's doing."

Given opportunity to stay out of jail

During Monday's Supreme Court appearance, Justice George Murphy asked Hunter whether she would stay away from the megaproject sire if she were allowed out of custody.

Hunter said no.

The other three people who appeared in court Monday alongside Hunter were asked the same question, and replied that they would keep from impeding the project. They were allowed to leave.

"I am concerned for her because she is a mother, she is a grandmother and she is alone," said Saunders-McLean, who says she inhabited the main Muskrat Falls worksite along with Hunter and a number of others last October.

After that protest, which shut down the construction site for a number of days, Saunders-McLean and Hunter signed the same undertaking committing to the court to stay a kilometre away from all Muskrat Falls sites.

"The reason why I came [to the gathering at the RCMP building] is to show that we are still here and we're not going away," said Saunders-McLean.
